,To all whom t may concern.'

Be it known that I, Louis liiiLLEn, of Rochester. in the county ofMonroe and State ot' New York, have invented certain new and usefulImprovements in Electrical Communicatingr Systems; and I do herebydeclare the following to be a full, clear, and exact descril'ition otthe same. reference being had to the accompanying drawings` forming apart of thisA specification. and to the rcterenwnumerals marked thereon.

The present invention relates to electrical communicatiner systems andit has for an object to provide a system over which either lire alarmreports or calls may be sentor telcphonic communications may bemaintained. preferably having provision for giving preccdcme to the tirealarm reports.

Another object of the invention is to provide atelephone system in whichthe time of the call from a substation is automatically recorded inorder that the system mayv be f iployed for making records ot' the timesof the reports of policemen, watchmen and others who are required tomake periodical returns to central oliices.

still further object is to provide. a tire alarm system in which thesender of the alarm or call may be signaled that the alarm has beenreceived and in this way assured that the system is in workingcondition.

To these and other ends the invention consists in certain improvementsand combinations of parts all as will be hereinafter more fullydescribed. the novel features being pointed out in the claims at the endof the specification.

In the drawings: Figure 1 is a diagrammatie view of one line of atelephone system designed for recording the times of the reports ofpolicemen or Watchmen, there being combined therewith means adapting theline for the transmission of fire alarm signals; Fig. Q is adiagrammatic view of the central oliiee apparatus for connection to theline; Figi. 3 is a detail view of one of the time recording,Ymechanisms, and Fig. 4 is a diagrammatic view of a line in the systemdesi ned for use in a factory or other large bui ding or plant in whicha watchman or watchmen travel from station to station and report at cachstation, the report being automatically recorded in the building andalso at some central point, such as a telephone oiee or police station.

In the embodiment of the invention illustrated in Fig. 1 each line ispreferably a normally closed circuit having a substation and a centralstation and comprising line conductors 1 and 2 and a suitable source ofenergy, such as central station battery 3; a high resistance comprisingin this instance resistance coil L'l and the windings of a signal orelectromagnetic bell 5, being preferably arranged in the circuit..Bridged across the circuit in order to short circuit the high resistanceis a telephone instrument set comprising a transmitter (i connected tothe lines 1 and 2 by a conductor 7 having a primary coil S thereinacti-ing on the secondary coil 9 which is connected to the receiver 10,the receiver being preferably supported as usual upon a hook l1 whichcontrols switches l2 and cuts out the instrument set when the receiveris arranged on the said hook. The branch in which the instrument set ispositioned may also be provided with switches 13 which have a normaltendene)v to close and are controlled by the door 14 of the inclosnre 15thaty houses the instrument set and is pref crably locked so as to beaccessible only to authorized persons. It is apparent that when the door1l is moved to closed position the switches 13 will be moved to breakthe shunt circuit 7 thas cutting! outv the instrument set. The advantageof this arrangement is that the signal 5 may be operated from thecentral station in a manner to be described. even though the receiver 10has not been returned to its hook 11 through either design orcarelessness. Arranged Yat the central station to be operated on theremoval of the receiver 10 from its hook is, the operators signal orsupervisory, which in this instance. embodies a conductor 16 leadingrfrom line wire 1 to the lamp 17 and a conductor 1F. leading; from thelamp and connecting with a movable switch member 19 that is adapted tocrepe/rate with Contact Lt) oonnvvtvtl hy oontlurtor l with the Contart-'vl'hv vontuvt 2; is adapted to be vngagvtl hy tho arnnuurv witvh Q3which, hy votnllulor 2l. ronnvvl with .liltv wir@v 2. l Yl`hv opvrat'iouot thv armaturv myitvh 2?) may hv vtlvvtvfl hy onv polv ot' thv compoundwound vlvctrounagnvt '13.3 whosv wintlingrb urv arraugvtl in thvinuinlinv.

The lever 53 may bearranged CD i other and reports at each station. ln reporting he removesthe receiver l() which closes switches 12 and cuts out the highresistance 4. 5 thus energizing` electromagnets 25 and 4t. The lat'teractuates the time recording mechanism making a punch mark in the in'tains from the voice of'the sender whether the oroper person is makingthe report. ln coi .ecting with the line the central operator au;Iunatically extinguishes the lamp 17 and if the otlicer desires toconnect with another line the plug 38 is en'iployed, the denergizationof magnet causing the lamp 17 to be again 'illuminated to notify thecentral operator that the conversation has ceased. If the otiieer tailsto hang up the receiverl when he closes the door 14 the telephoneinstrument set will be cut out by the switches 1?, thus permitting thesubstation to be called. The calling of the substation is etliected bythe generator which connects with the line after the recording mechanismand the operator's supervisory has been cut from the line.

The tire alarm signalv may be sent by any one upon breaking' of theplate 59'. and pushing' of the button 5S. This breaks the normallyclosed line circuit and deiinergizes the magnet (33 which releases thesignal (50. The resistance -l. is yat the same time short circuitcd thusilluminating the lamp 1T and operating the recording mechanism. Thecentral operator thereupon presses bu ton #i3 to release switch 53 andoperate the signal 5 at the substation in order to notify the sender ofthe alarm that the call has been noted. The button 5S could be used forsome other purpose than a fire alarm call as it may he employed topermit private individuals to'call the police.

'hen the system is arranged in a factory or other plant the operation atthe central station is substantiallv the same. The removal of a receiveralso operates a record.- ine mechanism at the factory so that a completerecord of the reports of a Watchman or watchmen may be obtained at anytime while there is at all times a supervision being maintained at thecentral station.

A system constructed in accordance with this invention will addmaterially to the etti` ciency of a police force of a. large city as acomplete record of each otiicer may be obtained with very littletrouble, as each otticer on the line has an individual record, or inother words, one which is separated from tno others. t Any number ofreports may be sent in simultaneously withoutinterference,

as each substation has a separate connection with the recordingmechanism.' The approximate location of an otficer at' a particle lartime can be found out immediately and he may be called to headquartersmerely by signialingir the last substation at which he has reported orthe one at which he is next to report. It is impossible for the officerto send in a report by another party as he must talk with the centraloperator who will be familiar with his voice. The central operatorcannot interfere with his report favorably or otherwise as the recordingmecha nism is controllable only from the substation and the report ismade Whether the operator answers or not. The otlicer cannot offer as anexcuse for his failure to report that the line was out of Yorder whensuch is not the case for on the breakimgr of the line the centraloperator is signaled.

The fire alarm feature may take the place of the usual fire alarm systemor may be used in conjunction therewith when it will offer that muchtereater security against the spread of fires. Even should one of thelines get out. of order the whole system is not rendered inoperative aswith the present fire alarm systems and `the sender of the alarm isassured that the report has been received as he obtains a signal fromthe central otlicec lYhen the factory system is employed it is possibleto maintain constant supervision of the watchmen for should they fail tore.

port to the central operator immediately int quiry is instituted toascertain the reason therefor. Thilo the central operatorl cannot knowfrom which substation the report is sent in yet it can be ascertained byan inspection of the auxiliary recording mechanism whether the usualrounds have been made.

vhile the initial cost of this system is not greater than those atpresentl used. the cost of maintenance is less, and the 2greateretlieicncy secured both in police and in tire protection soon pays forits installation.
